Abstract
The method of quadrupolar nuclear acoustic resonance (NAR) allows to determine the tensor S relating the ultrasound-induced dynamic EFG (DEFG) to the ultrasonic strain. The observed temperature dependence of S in cubic Ta metal supports the "phonon-model" for the empirical T1.5-law of the nuclear quadrupolar interaction in metals.
